The main parameters for the inductor selection are the inductor value and the saturation current. To calculate the maximum inductor current under static load conditions, Equation 5 is given.
IOUT,MAX = Maximum output current
ΔIL = Inductor current ripple
fSW = Switching frequency
L = Inductor value
TI recommends to choose the saturation current for the inductor 20% to 30% higher than the IL,MAX, out of Equation 5. A higher inductor value is also useful to lower ripple current but increases the transient response time as well. The following inductors are recommended to be used in designs.
